I suppose I have to solve this: I don't know where to start

v=3k+5d solve for d
This is what I have

3K=5d=v
3k+5d-3k=v-3k
5d=v-3k
5d/5=v-3k/5
d= v-3k/5

Is this correct?

v = 3k + 5d

Moving the 3k to the left hand side, it becomes -3k, so we have

v - 3k = 5d

Now, let's divide both sides by 5.

(v - 3k)/5 = d

The only correction (though it's only a syntax error on here and probably looks crystal clear on paper) is the brackets around
(v - 3k)/5. When you write it like that, it's ambiguous, because it can either mean

v - (3k/5) OR
(v - 3k)/5

That is correct your answer.

v=3k+5d
v - 3k = 5d
(v - 3k) : 5 = d
d = v/5 - 3k/5

Not quite.
You need to put paretheses around v-k, so
d = (v-3k)/5

v - 3k/5 is qyuite different from (v-3)/5.

Use parentheses whenever there is a possibility your true meaning can be misinterpreted.

Your work should look like this:

v=3k+5d solve for d

5d=v-3k
d=(v-3k)/5

Mind the parenthesis.

v=3k+5d

Subtract 3k from both sides:
v-3k=5d

Divide 5 from both sides:
d=(v-3k)/5

This is correct!

no,it isn't.
d=v/5-3k/5 or d=1/5(v-3k)
